A special mask that allows you to mount Kasai 2.3x40 binoculars on your head and watch comfortably without using your hands.

The mask weighs only 70 grams thanks to the use of GFRP - a special composite reinforced with glass fibers and a polymer matrix. Although it looks weird, it is a great addition to the Kasai binoculars.

A quality mask made in Japan, just like the price - also made in Japan, because, as the manufacturer informs, they are made in small batches - several pieces - to order, by a local craftsman.
